Aluminum Extrusion Yield Loss Valuation and Inventory Accounting Baseline
Capitalize normal extrusion scrap net of recovery value into profile inventory while expensing abnormal press yield losses immediately to period P&L accounts.
Secondary Smelter Discount Schedule
Meaning
Metal recycling facilities maintain a list of price reductions applied to incoming scrap loads based on the presence of iron, plastic, paint, or other elements that increase the cost of purification. A secondary smelter discount schedule provides a transparent framework for valuing different grades of aluminium scrap relative to the clean commodity price. It outlines the specific penalties for contaminants that reduce the yield of the melt or damage the furnace lining.
This document is the basis for negotiations between scrap dealers and the smelting plants. The discounts are usually fixed per percentage point of contamination or as a flat rate per ton for specific categories of waste.
Contamination Assessment
When a truck arrives at the facility, the material is inspected to determine its quality and the appropriate discount from the list. The secondary smelter discount schedule is applied after the inspector takes samples and identifies any non-metallic attachments. Common issues include the presence of steel screws in window frames or thermal breaks made of polyamide.
These materials must be removed or accounted for in the final price because they do not contribute to the metal recovery. In some cases, the inspector may use a handheld x-ray device to check the chemistry of the alloy. If the scrap contains elements like zinc or copper that are outside the desired range, a further discount is applied.
This thorough evaluation ensures that the smelter pays a fair price for the actual metallic content of the load.
Pricing Structure
The financial impact of the contaminants is calculated based on the current market value of the primary metal and the cost of the recycling process. Within the secondary smelter discount schedule, the deductions are designed to cover the extra energy, labor and waste disposal costs incurred by the plant. For example, a load of oily chips will face a higher discount than clean dry chips because the oil must be burned off and the emissions must be treated.
The schedule is updated regularly to reflect changes in these operational costs. It also serves as a signal to the suppliers about which types of scrap are in high demand. By providing a clear pricing structure, the smelter encourages its suppliers to pre-sort and clean their material to achieve the highest possible return.
Supply Chain
Consistency in the application of the price reductions is vital for maintaining a reliable flow of raw materials to the furnace. The secondary smelter discount schedule helps build trust between the smelter and its network of scrap collectors and industrial manufacturers. Suppliers use the schedule to decide whether it is worth investing in their own cleaning and sorting equipment.
If the discount for a certain contaminant is very high, the supplier has a strong incentive to remove it before shipping. This leads to an overall improvement in the quality of the scrap entering the recycling stream. The smelter benefits from a more predictable input, which allows for better planning of the production cycles.
This interconnected system ensures that the circular economy for aluminium remains efficient and economically viable for all participants.
